Having problems with your 2003 Chevrolet Malibu ?
This morning we turned the heater on. When we turned the knob on the dash all that came out was cold air. We tried every setting on the postion for the air to come out. It still was the same
Well, the first thing to do would be to check the coolant level,do this with car cold.if the coolant is full then you may have a bad blend door actuator, a bad thermostant would do that but would get hot after a while of driving. if you drove for a while and still had no heat then it may be a bad blend door actuator or low coolant level,and last a plugged heater core.
Your thermostat may have gone bad. I have a 1999 Toyota Camry, had sim. problem, changed thermostat, fixed problem and was getting warm air again.
